Hierarchical packet fair queueing

Web1 de jul. de 2014 · In most systems, fair-queueing packet schedulers are the algorithms of choice for providing bandwidth and delay guarantees. These guarantees are computed assuming that the scheduler is directly attached to the transmit unit with no interposed buffering, and, for timestamp-based schedulers, that the exact number of bits transmitted … Web§ In what order are packets sent - e.g., FCFS, priorities, weighted fair-queueing § At what time are packets sent - e.g., Token bucket shaping Key observation § In many algorithms, the scheduling order/time does not change with future arrivals § i.e., we can determine scheduling order before enqueue 4

WebA network scheduler, also called packet scheduler, queueing discipline (qdisc) or queueing algorithm, is an arbiter on a node in a packet switching communication network. It manages the sequence of network packets in the transmit and receive queues of the protocol stack and network interface controller.There are several network schedulers … WebTo illustrate this idea, consider Hierarchical Packet Fair Queueing (HPFQ) [10]. HPFQ first apportions link capacity between classes, then recursively between sub classes be-longing to each class, all the way down to the leaf nodes.
